haye invented a new Automatic Air-Couplingfpevice', of which thefollowing is a speci V; ,juriction,with each other on the" principle of{r ghtand left, which shoes contain two gaskets, forming air-tightjoint, shoes held in is place by springs, air-supply through shoes,being controlled by leversfrom side of car,

which levers act in conjunction with present trated in thecoupling-lever; and the objects of cur invention are, first, to providean automatic aircoupler second, to afford facilities for control of airfrom side of car. We attain these objects by means of the mechanismillusaccompanying drawings; in which--- i Figure I is a view from theunder side. of the coupling. Fig. II is a side view" of the entire"device.
